Title: Sensor
Inventor: MORIMOTO SATOSHI
IPC: G01N27/12
Filed: 1987-10-02
Abstract: PURPOSE:To prevent deterioration in a sensor, by a method wherein the surface of a sensor body is covered with a breathing limit clad and a part of a gas diffused owing to oxidation activity of the sensor body is removed by oxidation to vary relative sensitivity to various gases. CONSTITUTION:A heat resistance insulating substrate 4 made of alumina or the like is provided with a pair of electrodes 6 and 8, a metal oxide semiconductor 10 made of SnO2 or the like and a heater 12 and a ceramic spray coated film 14 as breathing limit film is applied on the entire surface of the semiconductor 10 as sensor body. In this manner, when the surface of a sensor 2 is covered with a film 14, the diffusion of vapor of an organic solvent to the semiconductor 10 is limited. On the other hand, the semiconductor 10 or the like has an oxidation activity to the organic solvent, and hence, vapor of the organic solvent is lowered within the semiconductor 10 because of a balance between the diffusion and oxidation. Then, deterioration in the sensor 2 can be prevented by lowering the density of vapor of the organic solvent within the semiconductor 10. Detection sensitivity will not lower regardless of a drop in the density of a gas within the sensor 2. This enables the prevention of deterioration in the sensor otherwise caused by the vapor of the organic solvent with a high density without lowering detection sensitivity.

Title: Method and means for purifying living organism in water
Inventor: GERUHARUTO RIHAINERU
IPC: C02F3/10
Filed: 1993-10-06
Abstract: In the process, water containing organic carbon, ammonium and nitrate is biologically purified. In a first reaction vessel (10), forming a denitrifying biofilm reactor, the majority of the carbon is eliminated under partly anoxic, partly aerobic conditions with utilisation of nitrate oxygen or molecular oxygen. In a second, aerated reaction vessel (20), the ammonium is at least partly converted into nitrates by nitrifying organisms. Nitrate-containing water is returned from the second reaction vessel to the first. The water to be treated is conducted in the first reaction vessel from top to bottom over a flooded fixed bed. To supplement a deficiency of nitrate oxygen in the carbon elimination, the solid bed is aerated in the bottom region with a gas which contains a metered portion of molecular oxygen. The process according to the invention is particularly suitable for the purification of waste water (effluent) which has a variable ammonium concentration. <IMAGE>
